Description

TECHNICAL FIELD

[0001] The utility model relates to fire smoke exhaust fan technical field, specifically, relate to a centrifugal fire smoke exhaust fan. BACKGROUND

[0002] The weight of the cabinet type fire centrifugal fan can be significantly different due to specific models, structural sizes, and configuration differences. Generally speaking, the weight of such fans is approximately in the range of 85 kg to 730 kg. For small cabinet type fire centrifugal fans, given their relatively light weight, conventional handling tools such as trolleys, forklifts, or hydraulic handling vehicles can be used during transportation. However, for large or heavy cabinet type fire centrifugal fans, due to their enormous weight, the above-mentioned conventional handling tools often cannot meet the transportation needs. In such cases, cranes, hoists, or professional handling equipment must be used.

DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-3 As shown, a centrifugal fire exhaust fan includes a base plate 100. The bottom of the base plate is provided with the exhaust fan body 101 and the motor 102. This technology is existing technology and will not be described in detail.

[0022] In at least one embodiment, four sets of support members are formed on the base plate, and an air cushion transport vehicle 200 is inserted into the support members. A limiting mechanism is provided on the support members to prevent the air cushion transport vehicle from detaching from the support members. The air cushion transport vehicle is existing technology; a Longsheng brand LHQD-10-4B air cushion transport vehicle can be directly purchased, and this air cushion transport vehicle can be disassembled and reused with other centrifugal fire exhaust fans.

[0023] In at least one embodiment, the support member includes a left support plate 11, a right support plate 12 and a rear limiting plate 13. The rear limiting plate is provided between the left support plate and the right support plate. Dovetail grooves 21 are formed on the left support plate and the right support plate. Dovetail sliders 2 that cooperate with the dovetail grooves are provided on both sides of the air cushion transport vehicle. The dovetail sliders cooperate with the dovetail grooves.

[0024] Furthermore, the left support plate 11, the right support plate 12, and the rear limiting plate 13 are all fixedly connected to the bottom of the base plate.

[0025] Furthermore, the ends of the left and right support plates are provided with limiting mechanisms.

[0026] In at least one embodiment, the limiting mechanism includes a rotating shaft 3. Taking the right support plate as an example, as follows... Figure 2 As shown, a rotating shaft is installed on the right support plate, and a limiting plate 4 is rotatably connected to the rotating shaft. The limiting plate is provided with a positioning hole, and a limiting bolt 5 is installed in the positioning hole. Correspondingly, the right support plate is provided with a limiting threaded hole 51.

[0027] Furthermore, the limiting plate can rotate so that the positioning hole and the limiting threaded hole are coaxial, and the limiting bolt passes through the positioning hole and is threaded into the limiting threaded hole.

[0028] In at least one embodiment, the left support plate and the right support plate are provided with a side locking mechanism.

[0029] Further, as shown in Figure 3 The side locking mechanism includes a locking bolt 6, and the dovetail sliding block is provided with a matching insertion hole. The left support plate and the right support plate are provided with locking threaded holes matched with the locking bolt.

[0030] The locking bolt can be threadedly connected in the locking threaded hole and the end of the locking bolt is inserted into the matching insertion hole.

[0031] The working mode ensures that the bottom plate, the support member, the air cushion carrier, the limiting mechanism and the side locking mechanism are complete and undamaged. It is confirmed that the air cushion carrier (such as the LHQD-10-4B of Longsheng brand) is in good working condition, and the air cushion module has no air leakage phenomenon.

[0032] The air cushion module of the air cushion carrier is placed under the bottom plate support member according to a reasonable layout. In order to protect the air cushion module, a wooden board can be added above it. The main air pipe is connected with the air source and the air regulator, and the auxiliary air pipe is connected with the air regulator and the air cushion module. Turn on the air source, adjust the pressure regulating valve knob of each air cushion, and make the air cushion inflate and rise. Note that the inflation pressure should not exceed 0.35MPa to prevent the air cushion from vibrating up and down. The dovetail sliding block on both sides of the air cushion carrier is aligned with the dovetail groove of the support member to ensure stable insertion.

[0033] Taking the right support plate as an example, rotate the limiting plate on the rotating shaft to make the positioning hole coaxial with the limiting threaded hole. Thread the limiting bolt through the positioning hole and threadedly connect it in the limiting threaded hole to ensure that the limiting plate is fixed. Threadedly connect the locking bolt in the locking threaded hole, and insert the end of the locking bolt into the matching insertion hole of the dovetail sliding block of the air cushion carrier. Confirm that the locking bolt is firmly fixed to ensure that the air cushion carrier and the support member are not loose.

[0034] After turning on the air source, the air cushion carrier suspends the equipment, and the staff can push the equipment to move. After the equipment moves to the designated position, turn off the air source, deflate the air bag, and remove the air cushion module from under the equipment. Discharge the compressed air in the main air pipe and the auxiliary air pipe, and collect the air pipe and the air cushion module.

[0035] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
